Chemical Structure

2-Propenoic acid, 2-methyl-, polymer with ethene, potassium salt CAS 26376-80-7 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

2-Propenoic acid, 2-methyl-, polymer with ethene, potassium salt (CAS 26376-80-7), molecular formula C4H5O2KC2H4 and molecular weight 152.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Propenoic acid, 2-methyl-, polymer with ethene, potassium salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
